JOHN O. WANDS, OF ST. LOUIS, MISSOURI.

CAR-TRUCK.

SPFGIFIOATION forming part of Letters Patent No. 717,304. dated.lDecember 30, 1902.

Application filed June 4. 1902. Serial No. 110,167. (No model.)

To all whom it may concern,.-

Beit known that I, JOHN C. WANDs, a citt zen of the United States,residing at St. Louis, Missourhhave invented acertain newand usefulImprovement in Oar-Trucks, Vof which the following is a full, clear, andexact description, such as will enable others skilled in the art towhich it appertains to make and use the same, reference being had to theaccompanying drawings, forming part of this specification, in Whichl 4Figure l is a cross-sectional view showing my improved car-truck inposition under a car. Fig. 2 is a top plan view of the truckti'ansoin.Fig. 3 is a side elevational view of the truck. Fig. e is a top planView of a modiied form of the carrier forn the sidebearings,l

and Fig. 5 is a sectional view onV line 5 5 of Fig. 4.

This invention relates to a new and useful improvement in trucksdesigned especially for the rolling-stock of railways, the object beingto carry the Weight of the car-body and its contents on frictionlessside bearings,vthns relieving the truck-transom of the Weight usuallyimposed thereon about its center through the center plate.

My invention consists in the construction, arrangement, and combinationof the several parts, allas will hereinafter be described, andY,afterward pointed out in the claims.

In the drawings, 1 indicates the longitudinal sills of acar-underframiug,` and 2 the iioor supported thereby.`

3 represents the body bolster or transom, which is preferably made ofcast-steel and is provided with bearing members 4, usually designated asthe upper side-bearin g members. Dependingfrom .this body-transom is acylindrical projection 5, which answers the function of a king-bolt andis the pivot upon which the truck turns when the car is making a curve.i

6 indicates the top arch-bars of the truck, 7 the lower arch-bars, and 8the tie-bars, of Well-known construction. The Wheels, axles, and joumal-boxes may be mounted, as usual, in the truck side frames.

9 indicates the column-bolts, which secure the arch and tie barstogether and also hold the truck transom or bolster in position.

The truck transom or bolster is shown more clearly in Figs. l'and 2 andconsists of acasting, preferably of steel, extending from'side to sideof the truck, said casting being formed with an opening about its middleto receive the pivot projection 5. This transom is made up essentiallyof a horizontalrweb 10, which is curved or arched in its center, asshown, depending flanges ll being arranged at each side thereof, whichflanges at their ends are formed with seats for the bottom arch-bar.Reinforcing-flanges l2 are arranged under the ends of the horizontal web10 in order to strengthen the spring-seats afforded by said web at theends of the transom. A vertical web 13 is also arranged at the ends ofthe transom above the bottom arch-bar for wellunderstood purposes.

14C indicates vertical webs extending upwardly from each side and at theends of the truck-transom, which vertical webs afford seats for the toparch-bar. The interior faces of these vertical webs are formed withvertical ribs 15, which serve as guiding-flanges for avertically-movable casting 16. Casting 16 is composed of a horizontalbottom plate, forming a spring-seat for springs 17, the upper face ofsaid casting being flanged and reinforced by the webs, so as to supportan antifriction side bearing 18, preferably at a point above thehorizontal plane of the top arch-bar 6. The construction of thisantifriction side bear# ing member 18 is preferably similar to thatshown in United States Letters Patent No. 590,286, granted to meSeptember 2l, 1397. There is a spring-supported casting lo at each endofthe truck-transom, so that the antifriction side bearings carriedthereby coperate with the bearing members 4f of the bodytransom, and inthis manner the car-body is supported practically at its four corners.

From the above it is obvious that the trucktransom can be madeexceedingly light, as the point where the load is applied isremoved fromthe center thereof, asis now generally practiced, and placed near eachend thereof, the load being distributed at these two points at each endof the car. By reinforcing this truck-transom in the manner shown anddescribed the same is made exceedingly strong for its weight and servesas an efficient tie for the side frames of the truck, holding said sideframes in rigid relation to each other.

IDC

By taking the load off of the usual center' plates and carrying it atfour points through antifrictiou side bearings the truck is enabled toreadily take the curves, which fact prevents derailment an d savesexcessive wear on the wheel-flanges.

In Figs. 4 and 5 I have shown a modiiied form of my invention in whichthe truck-transom is extended outwardly beyond the side frames or thearch-bars of the truck and provided with an additional set of verticalguiding-ribs 15u. The body-transom is provided With two top bearingmembers 4, which cooperate with antifriction side bearings 18a. There isa single casting 16n for supporting these side bearings, said castingbeing in the form of a yoke and being spring supported, as abovedescribed. In this manner the carbody is supported at eight points, thepoints of support at the four corners thereof being on both sides of theside truck-frames, whereby the load applied to each side truck-frame isdirect, being distributed equally on both sides thereof instead of onlyto one side, as inthe case of the construction shown in Figs. 1, 2, and3. In the construction shown in Figs. 4and 5 it will be obvious that thebodytransom need not be continuous from side frame to side frame of thetruck, as other means may be employed for tying said sideframestogether. Asamatterofconvenieuce,

however, I prefer to make the truck-transom in the construction shown inFigs. 4 and 5 continuous, so as to reduce the number of pieces enteringinto the truck construction.

I am aware that many minor changes in the construction, arrangement, andcombination of the several parts of my device can be made andsubstituted for those herein shown and described Without in the leastdeparting` from the nature and principle of my invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a car-truck, an arched cast-m etal transom comprisinga portionextending across the truck and forming spring-supports, springsthereupon, side-bearing supports resting on said springs and guided byupward extensions of said transom so as to be independently movablethereupon and antifrictional devices carried by said side-bearingsupports; substantially as described.

2. In a car-truck, an arched cast-metal transom comprising a connectingportion yextending across the truck, spring-seats upon the ends thereof,springs on said seats, side-bearing support-s resting on said springs,integral Webs forming guides on said transom for said side-bearingsupports, said bearing-supports being independentlyl movable, andantifriction devices carried thereby; substantiallyas described.

3. In a car-truck, a transom formed of one piece of metal and comprisingspring-seats, connections therefor extending across the truck,sidebearings at each side ofsaid springseats in combination with springs iusaid seats, side-bearing supports on said springs, and antifrictionaldevices carried thereby; substantially as described.

4. In a car-truck, a cast-metal transom composed of a horizontal webmember, vertical flanges for strengthening the same, a springseat,andrein forcing-flanges under the springseats, said reinforcing-flangesbeing recessed to receive the bottom arch-bars; substantially asdescribed.

5. In a car-truck, a cast-metal transom composed of an arched horizontalweb 10, depending flanges l1, reinforcing-flanges 12 and 13, verticalflanges 14 rising from the ends of the transom, and verticalguiding-ribsl, all of said parts being made in one piece; substantiallyas described.

G. In a car-truck, the combination with side frames, of a supportprovided with vertical guideways, a casting vertically movable in saidways, and side bearings carried by said casting, said side bearingsbeing located on each side of the side frame of the truck; substantiallyas described.

7. In a car-truck, the combination with a side frame carrying a supportprovided with vertical guideways, of a spring-supported casting movablevertically in said guideways, and side bearings carried by said castingand arranged on each side of the truck side frame; substantially asdescribed.

8. In a car-truck, the combination with side frames, of a transom ortruck-bolster extending outwardly therebeyond and provided with aplurality of guiding-ribs, castings extending on each side of the truckside frames and movable vertically between said guidingribs, springs forsupporting said castings, and side bearings carried by said castings oneach side of the side frame of the truck; substantially as described.

In testimony whereof I hereunto affix my signature, in the presence oftwo Witnesses, this 2d day of June, 1902.
